According to tradition it was the same Francis to indicate the place where he wanted to be buried. This is the bottom of the hill town where, usually, were buried in the "lawless", condemned by the justice (probably why it was called Collis hells). On that hill, which was later called Collis paradise was built the basilica that bears the name of the saint. The church had multiple purposes. First of all was the burial place of the founder of the order, which after just two years after his death was considered one of the most significant figures in the history of Christianity: that it arranged a suitable size to a popular place of pilgrimage and devotion. The relics of saints were usually placed in a crypt, but in the case of St. Francis made sure that the lower structure was as large as an entire church, so much to talk about a real lower basilica. A second set of interests was more closely tied to the papacy, who saw the Franciscan ideal allies to strengthen ties with the lower classes and popular. For this merged into the basilica needs related to the flows of pilgrims (amplitude, didactic set of representations) with the outline of a palace chapel (Chapel of the basilica was indeed papal) according to the latest Gothic influences, such as the Sainte-Chapelle in Paris where there are only two churches in the classroom. The construction of the basilica was started in 1228 by Pope Gregory IX and was completed in 1253 by Innocent IV. To complete the basilica offers came from all over the world and were called master architects, decorators and painters among the best of the time. In 1230, Francis's body was moved from the church of St. George (the future basilica of Santa Chiara) to be interred in the new basilica built in his honor. Assisi became, for all the pilgrims, a key step along the way to Rome. Since the saint was buried under the altar in a place inaccessible for centuries, it was lost the memory of the precise point where his body located, but in the nineteenth century it was found and carved out of a crypt.
